HI again,
I sat with our linux guy a bit and we plugged around, and found no mixup of
kernel-headers or compile environment. (that we could tell)
modprobe lnet works, and so do the others (listed in the original strace), but we found
that ptlrpc.ko is getting invalid argument.
from dmesg:

And on a non trace kernel it works:
open("/lib/modules/3.0.101-0.46-default/updates/kernel/fs/lustre/ptlrpc.ko",
O_RDONLY) = 3
stat("/sys/module", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0
stat("/sys/module/ptlrpc", 0x7fffce887520) = -1 ENOENT (No such file or
directory)
read(3, "\177E", 2) = 2
lseek(3, 0, SEEK_SET) = 0
fstat(3, {st_mode=S_IFREG|0744, st_size=2444032, ...}) = 0
mmap(NULL, 2444032, PROT_READ|PROT_WRITE, MAP_PRIVATE, 3, 0) = 0x7fe076d6d000
init_module(0x7fe076d6d000, 2444032, "") = 0
munmap(0x7fe076d6d000, 2444032) = 0
close(3) = 0
exit_group(0) = ?
Does this give more clues? Has anyone else run on a sles trace kernel?
